本発明は、電気掃除器に使用される矩形状の濾過エレメ
ントに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rectangular filter element used in a vacuum cleaner.
従来から、合成繊維等より成る帯状素材を断面が波形と
なるように順次折り曲げて連続したひだを設けた濾材に
、合成樹脂枠を一体成形した濾過エレメントは一般に使
用されている。BACKGROUND ART Conventionally, a filter element has been generally used in which a synthetic resin frame is integrally formed with a filter medium in which a band-shaped material made of synthetic fiber or the like is successively bent to have a wave-shaped cross section to provide continuous pleats.
ところが、この従来の濾過エレメントは、製造過程にお

濾材のひだが、枠の角部近くは曲って相互に密着したり
、或いは隙間ができたりして間隔が不揃いとなる結果、
濾過性能を害して商品価値を下げている。特にこの現象
は、精密濾過に使用される剛性の小さいガラス繊維濾材
において著しく、これが一般にガラス繊維濾材による樹
脂一体成形の濾過エレメントが作られない大きな原因で
あった。However, in the manufacturing process of this conventional filtration element, after integrally molding a synthetic resin frame surrounding the filter medium, when the resin is cooled to room temperature, the resin shrinks and the length of each part becomes 2 to 3% shorter. Each corner of is pulled in the vertical and horizontal directions, and the area near the corner becomes a curved surface as shown in FIG. 3, causing an error in the external dimensions. As a result, the folds of the filter medium were straight immediately after molding, but near the corners of the frame they are bent and come into close contact with each other, or gaps are created, resulting in uneven spacing.
It impairs filtration performance and reduces product value. This phenomenon is particularly noticeable in glass fiber filter media with low rigidity used in precision filtration, and this is a major reason why filter elements integrally molded with resin using glass fiber filter media are not generally manufactured.
本発明は、合成樹脂枠を用いた現在の直方体状の濾過エ
レメントに存する上記の問題に鑑みて、合成樹脂の収縮
の影響を濾材に与えることがな（、外形に狂いのない濾
過エレメントを得ることを目的としている。In view of the above-mentioned problems with current rectangular parallelepiped filter elements using synthetic resin frames, the present invention has been developed to prevent the effects of shrinkage of the synthetic resin from being applied to the filter medium (to obtain a filter element with a consistent external shape). The purpose is to
上記の目的を達するため、本発明の濾過エレメントは、
断面が波形となるように折り曲げ成形した濾材と、一対
の側板を形成する合成樹脂板又は金属板とに、合成樹脂
枠を一体成形したものである。In order to achieve the above object, the filtration element of the present invention includes:
A synthetic resin frame is integrally formed with a filter medium that is bent and formed to have a wave-shaped cross section, and a synthetic resin plate or metal plate that forms a pair of side plates.
そして、上記濾過エレメントの製造方法としては、断面
が波形となるように順次折り曲げて連続したひだを設け
た濾材と、濾材のひだの稜線に平行な一対の側板となる
合成樹脂板又は金属板とを配した後、これらに合成樹脂
枠を一体に成形する方法を用いる。或いは濾材に合成樹

に平行な一対の合成樹脂枠の側面を開放して一体成形し
、これが未だ冷却しないうちに前記開放側面に合成樹脂
板又は金属板を挟み込んで接着する方法でもよい。The method for manufacturing the above-mentioned filtration element includes a filter material that is sequentially bent so as to have a corrugated cross section to provide continuous pleats, and a synthetic resin plate or metal plate that serves as a pair of side plates parallel to the ridgeline of the folds of the filter medium. After arranging these, a method is used in which a synthetic resin frame is integrally molded onto them. Alternatively, when integrally molding a synthetic resin frame to a filter medium, the sides of a pair of synthetic resin frames parallel to the ridge lines of the folds of the filter medium are opened and integrally molded, and the synthetic resin is applied to the open sides before the frames have cooled yet. A method of sandwiching and bonding plates or metal plates may also be used.
上記のように構成された濾過エレメントは、予め用意し
た濾材と側板に、側面が開放された合成樹脂枠を一体成
形するため、合成樹脂枠収縮の影響を受けることなく、
従って外形寸法に狂いを生しることにより濾材のひだが
不揃いとなって濾過性能を害するということがない。The filtration element configured as described above is not affected by synthetic resin frame shrinkage because the synthetic resin frame with open sides is integrally molded on the filter medium and side plate prepared in advance.
Therefore, there is no possibility that the folds of the filter medium will be irregular due to irregularities in the external dimensions, thereby impairing the filtration performance.

3.15 and 14.16 between the respective rear ends of struts 17 and 18
The side surfaces 3a and 3b and the front and rear surfaces are integrally molded with the front and rear surfaces open. The filter medium 2 is made of a belt-shaped material made of synthetic fibers, etc., which is sequentially bent at equal intervals from one side 21 to the opposite side 22 so that the cross section becomes a waveform, forming continuous pleats. Both sides 3a of the synthetic resin frame 1
and 3b are included so as to be parallel to each other. The side plates 3 are made of synthetic resin or metal, and are attached to both sides 3 of the synthetic resin frame 1.
It is integrally molded with the synthetic resin frame l so as to serve as a side plate that closes a and 3b.

製作することが可能となった。Since the present invention is constructed as described above, when the synthetic resin frame is integrally molded, the outer shape of the frame is not affected by resin shrinkage, and therefore the filter medium can be installed accurately, resulting in a filter element with good filtration performance. In particular, it has become possible to manufacture a filtration element integrally molded with resin using a glass fiber filter medium with low rigidity used for precision filtration, which was previously impossible to manufacture.
